chemical_vae install

[mitangguoguon]

Hi all, I have installed chemical_vae by the following commands:**

"~/anaconda2/bin/pip install -r requirements.txt ~/anaconda2/bin/conda env create -f environment.yml source ~/anaconda2/bin/activate chemvae python setup.py install"

When I enter the instruction "python -m chemvae.train_vae", It gives the following errors:

_"/home/lili/anaconda2/envs/chemvae/lib/python3.6/importlib/_bootstrap.py:219: RuntimeWarning: compiletime version 3.5 of module 'tensorflow.python.framework.fast_tensor_util' does not match runtime version 3.6 return f(*args, **kwds) /home/lili/anaconda2/envs/chemvae/lib/python3.6/site-packages/h5py/init.py:36: FutureWarning: Conversion of the second argument of issubdtype from float to np.floating is deprecated.

How can I solve this problem? Thank you very much.

The issue is due to the fact that one of the layers has only been written in Tensorflow (and not Theano). Please set the Keras backend to Tensorflow and it should work.

"export KERAS_BACKEND=tensorflow" command in the terminal will do.
